PURPOSE:To cope well with load changes of a fuel cell and prevent the performance degradation and breakage of it by providing a nozzle-opening correction means to make fine adjustment of the opening of the variable nozzle of a turbine so that the air pressure detected by a pressure sensor will converge to a certain value. CONSTITUTION:A pressure sensor 24 is set in an air chamber 9 of a fuel cell 2, and also a nozzle-opening correction device 25 is set to make fine adjustment of a variable nozzle 13 based on the signal (a) from this pressure sensor 24. The nozzle-opening correction device 25 is equipped with CPU26, which compares the air pressure value detected by the above pressure sensor 24 with the previously set value and then outputs a command signal (b) to reduce the difference between them to zero, and an actuator 27, which changes the opening of the variable nozzle 13 based on the command signal (b) from this CPU26. |
